Copper Flotation
Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two … See more
The Extraction of Copper
Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation). Figure 1: Chalcopyrite extracted from Zacatecas, Mexico. from Rob Lavinsky (iRocks) under a CC-BY-SA-3.0 license.
60 Centuries of Copper: The Flotation Process
The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...

Improving Flocculation Performance of Copper Flotation …
Large amounts of tailings are produced when copper minerals are concentrated by flotation. For instance, the flotation process is performed with water containing 25–35% wt solid ratio and is consumed 1.9–3 m 3 water per ton of ore processed (Gunson et al., 2012; Li et al., 2019).
Prediction and Optimisation of Copper Recovery in the …
A hypothetical optimisation solution assessment showed that SA provides the best set of solutions for the maximisation of rougher copper recovery, obtaining a throughput of 638.02 t/h and a total net gain percentage of 14%–15.5% over the other optimisation algorithms with. a maximum copper recovery of 94.76%.
Column Flotation of Copper
As an example, the copper flotation columns were operated with holes in the sparger fabric for a period of time. The overall results attained with the single stage copper flotation columns are …
How to Recover Copper from Slag by Flotation
Recovery of copper in concentrates from slags cooled in the induction furnace and ground for 30 minutes ranged from 87.1 to 96.2 percent with the best recovery obtained on the highest grade slag sample. Copper content of the flotation tailings, which is the most important indicator, ranged from 0.26 to 0.39 percent.
Development of a new algorithm for segmentation of flotation froth images
The developed algorithm is validated using some froth images captured at different operating conditions, so the results indicate that the method can segment the mixture of big and small bubbles effectively. It is well known that froth visual features reflect the operating conditions of the flotation process, so that being able to accurately obtain …

The copper ore flotation method can be divided into forward flotation and reverse flotation according to the separation of valuable components: discharging …
The interaction of clay minerals with gypsum and its effects on copper
Fig. 2, Fig. 3 show copper grade as a function of copper recovery, and gold grade as a function of gold recovery, respectively, from the flotation of the ore and its mixtures. The main observation was the poor flotation outcome that resulted from the mixture with bentonite and its change after gypsum addition. The baseline flotation of …
Flotation of copper oxide minerals: A review
The fresh copper oxide mineral surfaces exposed during crushing and grinding have a significant effect on subsequent flotation [23], [24], [25], [26].Many dangling bonds exist on fresh mineral surfaces because of destruction of the original lattice bonds, and the copper oxide mineral surface often shows strong polarity because of the …
An unsupervised method for extracting semantic features of flotation …
The froth feature extraction plays an important role in flotation circuit monitoring. Given the low efficiency of hand-crafted features and the poor interpretability of high-dimensional features extracted by convolutional neural networks, an unsupervised method for extracting human-understandable semantic features of flotation froth images …
Effect of Collector & Frother Concentration on Copper Flotation
The flotation process may be considered an interactive system consisting of many chemical, operational, and equipment variables. Changing any one of these variables causes an overall system response change. This study examines the effects of simultaneously changing the operating variables of: (1) frother concentration and air flow …
Closing the Loop in Ion Flotation: Recovery of Copper
Ion flotation is an efficient separation technique for the recovery of metal ions from dilute aqueous solutions. Provided that both the collected metal and the surfactant are recovered from the phase, it could be considered as an alternative to ion exchange, adsorption or solvent extraction in hydrometallurgy. However, most studies …
